There are many landforms found in Africa. Africa has the Atlas  Mountains, the Congo River Basin, the Nile River, and the Sahara  Desert.
Eastern Africa consists largely of plateaus and has most of the highest elevations in the continent. The two most striking highlands are in Ethiopia and Kenya, respectively, where large areas reach elevations of 6,500 to 10,000 feet (2,000 to 3,000 metres). Twin parallel rift valleys that are part of the East African Rift System run through the region. The Eastern, or Great, Rift Valley extends from the Red Seaâs junction with the Gulf of Aden southward across the highlands of Ethiopia and Kenya and continues on into Tanzania.
